190cc and innovative tuning questions

[Younger1993]

So I just installed my 190cc injectors on Friday, and uploaded Erics xtreme street program and boy does this thing pull! My question is I noticed it will rev up to or a smidge above 4,000 rpm's! I have a stock block...does that seem right? or is that real dangerous to do without springs and pushrods...????

I reved over 4850 with my 190s plenty of times. But that being said keep it under 4500.

holy crap man, i have mine set to 4k, erics tune default was at 4150... is it ok to run a stock block that high? I've "heard" the low pressure oil pump gears dont like it. I would def love a few more RPMs.

you could give it alittle more but do at your own risk.

Eric sets all his stuff at 4150'ish because that's a safe spot for a stock motor, or I should say as safe as you can expect for performance tuning... I know there's a little more in the bottom end.

But like said before, raise the limit at your own risk.

lol then i might just stay at 4k probably wont even use the default 4150... i have new heads but im sure they reused my old pushrods and even new push rods im sure wouldnt be happy with huge revs unless upgraded.

damn i just searched online, you can get push rods and springs for around a $1k, i wish they wouldve told me that when i got new heads, wouldve been nothing to have them toss those in for the long haul mods...

I talked to Eric, my rev limiter was set to 4150 too! except when I bump mine down to 4000, it wont shift, and it just bounces on the limiter. He said my commanded shifts are set at 3800..and its my tachometer thats off. While my question is, how does the tach not show the correct RPMs but the engine is 'supposedly' shifting at 3800. and the rev limiter is even set at 4150! so I am just confused...and I dont want to f' my motor up..

when i set mine at 4000 it wont shift, and it just keeps bouncing at 4k, swoleguy, how did you get the truck to shift at 4000 instead of 4150 once you dropped the rev limiter

I've got mine set at 4350 FWIW. Try raising it up a notch and see if the problem goes away. If not you might need Eric to adjust your file a bit.
